BOX-MACHINE.

SPECIFICATION forming part of Letters Patent No. 629,783, dated August 1, 1399.

Application filed March 4,1399.

To all whom it may concern:

Be it known that I, EUGENE FANNING, a citizen of the United States, residing in the city of Newton, county of Middlesex, and State of 5 Massachusetts, have invented a new and useful Box-Machine, of which the following is a full and exact description,reference being had to the accompanying drawings, forming a part of this specification, and to the-letters of refro erence marked thereon.

My invention relates to improvements in machines for pressing the cemented or pasted scams or joints in paper and other boxes and" holding them in proper form while the'paste r 5 or other adhesive substance is setting or bealso a perspective viewof part L of one of the pivoted or hinged compression-plates; Fig. 3, a similar View of an opposing similar plate and a box in operative relation; Fig. 4, siniilarly the hingedpressure plate or head g, to which pressure-plate t' is hinged or pivoted.

Fig. 5 shows in part plan both parts g and i' and hinge part Z. Fig. 6 illustrates one of the many forms which may be used in the hinging or pivoting of the pressure plates and 40 heads. Fig. 7 is an elevation of hinged pressure-head g inverted.

Like letters refer to the same or corresponding parts in all the figures.

The base of the machine is marked a a and on the left is provided with the side guide I). When this side guide needs to act nearer the middle oft-he machine, a looseblock may be used; as indicated by the dotted lines marked Block. A head-block c at the left pro- The mechanism for-accomplishing the ob-' Serial No. 767,815. (No model.)

vides support for cam 12 and for hinge h, retracting-spring m, and pawl j, hinged at 7c. An open slot or race is provided lengthwise in the middle of the base, which contains and forms a guide for the ratchet-slided. To the end of this'slide is firmly fixed the abutment or pressure head e, and to this is pivoted the pressure-plate f. A pawl j is provided to mesh in the ratchet-slide d. This pawl is hinged or pivoted to head-block c. The slide may be elongated for a guide. (See dotted lines.) Opposed to pressure-plate fand pivoted to pressure-head g is the pressure-plate 'i. .The pressure-head g is hinged or freely jointed at hto the head-block-c. A spring m of any suitable construction is applied between pressure-head g and the head-block c and operates to keep the pressure=head g in contact with cam n, so that when the cam is operated on its return stroke the head 9 and plate'iwillreturn simultaneously. Any other suitable connection to the cam may be used to cause this return. of the pressure-plate i coincidently with the return movement of the cam after pressure is relieved. The cam 72 is journaled to the head-block 0, so that 75 when the cam-handle is drawn forward it throws forward the pressure-head g and the plate 1', so as to apply the requisite pressure upon a box placed between the pressure-plates 11 and f, and these plates, by reason of their central pivots, will readily adjust themselves to the difierent angles which may be adopted for different boxes. An illustration appears in Figs. 2 and 3. A former-block having the required angles for the box is usually placed inside the box when the pressure is applied and insures the proper angles required being formed by the self-adjusting pressure-plates 2' and f.

The ratchet-slide d and inter-meshing pawl 0 j serve to adjust plates & and f to any required distance apart for different sizes of boxes.

In operating the improved-machine the box to be given its final form has the cement or paste applied to the laps or seams and is ad- 5 j usted upon a form-block and placed between the plates 2' and f. Thenthe-plate'f and slide at are brought backwardtill'theplates and box are in contact, when the pawl j engages and holds the slide 01 and thereby the head 6 and plate f. Then on drawing forward the cam-arm the required compression is produced and retained until the cam is thrown in reverse direction. The parts may be mostly of wood, or the whole may be of metal, if preferred. The preferred form of pivot for the plates is shown in Figs. 1 and 5, but various others may be used.

What I claim, and desire to secure by Letters Patent, is as follows:

1. The improved box-machine constructed with a bed carrying a detent-pawl and in a guiding way the slide-ratchet having the pivoted-together angulanbacked and fiatfaced press plates, the opposed similar pressplates hinged to the bed and provided with the impelling-cam and retractor-spring substantially as shown and described. 7

2. In a box-machine the fiat-faced doubleangle back pivoted-together pairs of pressureplates in combination with the slide-ratchet andpawl for one, and the hinged extension, cam and spring for the other, substantially as shown and described.

3. In a box-machine the combination of a bed, a ratchet-slide guided therein, its detentpawl, said slide having a double-plate pressure-head formed of two flat-faced doubleangle-backed press-plates pivoted together at the ridge formed by the intersection of said back angles and a similar double head swinglVitnesses:
